EMlLE F. VERDEL,

OF MEMPHIS, TENNESSEE, ASSIGNOR OF ONE-HALF TO FRANK OZANNE, OF SAME PLACE.

SPECIFICATION\forming part of Letters Patent No.362,47l, dated May 3, 1887.

pplication filed January 2 1, i886, Serial No. 189,319. (No model.)

to letters or figures of reference marked there on, which form a part ofthis specification.'

This invention relates to that class of mechanism designed to tin-wire the edges of `sheet-metal vessels or articles-that is, to roll the edge of the metal upon itself to give it the appearance of being wire-edged. Machines B and C are secured.

now on the market designed to accomplish this work are so costly as to be out of the reach of the majority of tin-workers, and they require to be operated by a skilled Workman.

rlhe objectof myinvention is to produce an inexpensive hand-machine, by means of which the edges of tin and other light'sheet metal may be tin-Wired? by unskilled labor; and my invention consists in the construction and vcombination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a side view of a machine for forming joints on sheet metal and beading said joints. Figs. 2 and 3 are end views, and Fig. 4 is a sectional view, of the'rotating heads. Figs. 5, 6, and 7 are detail views illustrating the progress of the work on a vessel.

A refers to the base of the implement, which is provided with outwardly-projecting lugs or ears a, with perforations which form a means for securely attaching the same to a work bench or stand, and said vbase-plate is provided at -its upper edge with a dovetailed projecting portion, b, upon which the movable standards Said base-plate is also provided with anopening between said standards, through which a rod of atreadle passes. The standard B is adapted to iit over the dovetailed portion of the base, and has formed thereon a downwardly -projecting screw-threadedl member, with which a screw-threaded shaft engages for adjusting the same longitudinally upon the base-plate, said shaft being provided near its end with a hand-Wheel for turning said scrcw-threaded shaft so as to adjust the standard B when desired. The standard C may have a similar-attach ment, though l prefer to secure the same, after being adjusted, by a set-screw,

tions in the bed-plate.

rIhe standard B extends upwardly and has formed therein a hearing for a vertical shaft, D, which is tapered at its upper end, as shown at d, the lower end resting upon a bearing formed near the lower end of the standard, and adjacent to the same the rotary shaft is provided with the pinion e.

The standard B carries a member, B', which projects vertically from the base thereof, the upper portion of said member B forming a bearing for a horizontal shaft, F. This shaft F passes through a bearing in the standard C, said bearing being on a line with the bearing 4in the member B', and the end of said shaft has a suitable crank-handle keyed thereon for rotating the same. It will be noted that when the crank-handle is rotated this rotary motion will be imparted to the vertical shaft D 5 also, that the standard C may be adjusted upon the base-plate, and `when so adjusted it will slide uponthe horizontal shaft. y f

The upper portion of the standard C has formed thereon a socket, and within said socket is adjustably secured a forked headpiece, C', between the armsof which is -pivoted a lever, E, said lever carrying at its end a Wiring-roll, H, which is journaled thereon so as to be at an angle with the lever, as shown. Between the bearing of this wiring-roll Hand its pivoted end are attached rods G, which extend downwardly and are connected to each other by a cross-plate, g, a rod, G', being attached to said cross-plate centrally, and extends downwardly through the base-plate, beheath which it is connected to a treadle or lever. A spiral spring, which has a tendency to throw the lever E upwardly, is located between the cross-plate g and the bed-plate, so as to normally hold the lever E and its wiringroll in a raised position. v

c, which may engage with threaded perfora- IOC l, as shown in dotted lines in Fig. l, refers to a form which corresponds in configuration with the shape of the article to be placed thereon, and said form is provided centrally with a tapered opening, by means of which it is rigidly secured to, though removable from, the tapered end d of the vertical shaft D, and the roll I-I is adapted to Contact with the edge thereof when forced upon the same by the treadle, hereinbefore referred to.

rlhe article to be wired, after being doubleseamed, is placed upon the form I, the edge to be beaded fitting close and projectinga distance equal to the circumference of the bead above the top of the edge of the form l'. lressure is then applied on the treadle, which brings the edge s of the roll ll against the metal which projects above the form I at the proper angle to turn said projecting edge outwardly. The shaft F is then turned, which imparts a rotary motion to the form l, and the friction causes the roll H to revolve, the rolling motion thereof and the pressure forcing the tin to follow outward and downward the outline of the groove u in the roll H, the lower edge or flange, l, preventing the spreading of the tin below the beaded edge until the upper flange, s, rests on the edge ofthe die J. The bead or wire edge now being completed, the pressure is removed from the treadle and the spring forces lever E, with its roll H, upward, so that the article which has been tin-wired can be removed from vform I and another one substituted.

Vhat I claim as new, and desire to Secure by Letters Patent, is-

l. In a machine for tin-wiring the edges of sheet-metal vessels, the combination, substantially as described, of the revolving ferm for carrying the vessel to be operated upon, and a tin-wiring roll provided peripheraily with a central groove or recess terminating at one side in a gradual curve and at the other side meeting the beveled peripheral. face of the roll at a sharp angle, whereby the edge of avessel may be coiled upon itself without wiring.

2. The combination, in a machine for tinwiring or beading sheet metal, of a roll, H, having a groove, u, and projecting portions s and i", adjacent to said groove, said roll being carried bya pivotcd lever which is adjustable vertically, and a rotary roll, l, adapted to carry the work and rotate the same against the roll H, substantiallyas shown, and for the purpose set forth.

3. In a tin-wiring machine, a roll for turning the edges of sheet metal upon each other, having a semicircnlar recess formed at its central portion, one edge of the periphery being curved adjacent thereto, while the opposite edge is formed at an angle, substantially as shown. and for the purpose set forth.

Llr. ln a tin-wiring machine, a base-plate, A, provided with standards ll and C, which are adjustable upon the base-plate independent of each other, a vertical shaft adapted to be rotated and receive a form, as set forth, and an adjustable lever, E, pivotally attached to the standard C and carrying at its end a peripherally-grooved roll, which is attached to said lever at au angle therewith, substantially as shown, and for the purpose set forth.

5. The combination, substantially as described,ofthe bedplate,thestaudards mounted adj ustably thereon, a vertical shaft or spindle journalcd in bearings in one of the standards, a horizontal shaft geared to said vertical shaft and mounted in bearings near the base of both standards, the head-piece adjustably secured in the socket of standard C, and the leverpivoted at one end to the head-piece and provided at the other end with a revoluble spindle.

In testimony whercofl affix my signature in presence of two witnesses.
